>>5366I'm in the same boat, so I'll jot here what I write for myself:
What do you mean by "the most out of life"? If money, be involved in business. If helping, go volunteer. If learning, read smart books and ask smart people. If laughing, visit a club or show.
If you don't know, that's great! There's truth in "I know that I know nothing." But don't let humility stop you from wandering around! It's a wonderful life :)
